The files contain the information of the outline of the shapes for each optimised geometry. All geometry dimensions are normalised using the upstream width of the design, W_{u}. The geometries investigated are characterised by a contraction ratio CR=8, a normalised contraction length, l_{c}/W_{u}=2.0, and are examined for Pressure-Driven and Electro-Osmotic flows. Moreover, this configuration was examined for both 2D and 3D flows. The dimensionless total length of the given shapes is L/W_{u}=21.0 For the 3D flows the aspect ratio AR is defined as w_{u}/depth. The information is given in two different formats: > Geometries.xlsx : Excel file that contains the shapes of all the optimised geometries. Pressure-Driven flows : > 2D_PD.dat: Optimised geometry for 2D > AR1.dat: Optimised geometry for AR=1 > AR2.dat: Optimised geometry for AR=2 > AR4.dat: Optimised geometry for AR=4 > AR8.dat: Optimised geometry for AR=8 Electro-Osmotic flows: > EOF.dat: Optimised geometry for 2D The optimised shape for EOF was also examined for 3D flows and it was found that is applicable for a range of aspect ratios, 1< AR <8.
